SPECIFICATION forming part of Letters Patent No. 654,964, dated'du'ly 31,1960.

Application filed March 9, 1899. Serial No. i08,368. (No model.)

To aZZ whom it may concern:

Be it known that I, JEFFREY T. FERRES, a citizen of the United States of America, reside ing at the city of Anderson, in the county of Madison, in the State of Indiana, have in vented a certain new and usefulImprovement in Paper-Outting Machines, of which the following is a description, reference being had of this specification.

My invention relates more particularly to that class of machinesin which a'web of paper continuously fed to the machiue is out both longitudinally and transversely into pieces of the desired size; but some of the features of my invention have relation solely to the longitudinal cutting of the paper and others solely to the transverse cutting of it and may be employedin machines capable of to the accompanying drawings, forming part cutting the paper one way, but not the other.

My machine has also been designed more especially for cutting corrugated paper and been used by me exclusively for that purpose,

but several features of my invention are applicable as well to machines for cutting other paper or, indeed, other materials than paper. Its novelty will be hereinafter set forth, and particularly pointed out in the claims.

In the accompanyingdrawings, Figure 1 is" a side elevation of the machine; Fig. 2,a top the forward left-hand corner of the feed-table, showing the forward end of one of the laterally-adjustable guides for the paper; Fig. 5, a detail side elevation of the front end of the machine opposite the side shown in Fig. 1; Fig. 6, a detail vertical section on the line 6 6 of Fig. 2; Fig. 7, a detail of one of the detachable cutting-scorers; Fig. 8, details of one of the creasing-scorers; Fig. 9, a side elevationbf one of the guides, and Fig. 10 an enlarged sectional detail of the ratchet-drum ofthe feed-roller. i Y

The same letters of reference are used to parts in the several views. I

A is the framework of the machine, which i I supports at its forward end the feeding and cutting mechanisms and in rear thereof the horizontal feed-table B, over which the strip of paper to be cut is drawn from a supplyroll 0, supported in bracket-arms D upon the rear endof the machine. In its forward movement over the table B the strip of paper.

0 is confined laterallyand properly guided bars E, Figs. 1, 2, 3, and 4, which carry at their front and rearends inverted screws F, whose fiat heads are confined in transverse T-slots G across the front andrear ends of the feed-table l3 and whose upper ends have threaded upon them thumb-nuts H, by means of which the guide bars may be securely clamped in their dilferent adjusted positions, according to the width of paper to be guided by them. r p r Secured upon the two longitudinal side bars of the frame at the forward end of the feed table B are two vertical posts or standards I, which are vertically slotted to receive the .vertically-adjustable bearings of a pair of feed-roller shafts J K, Fig. 1, the former of which are carried bythe lower ends of rods J extending through cross-heads on the tops of the posts I andverticallyadjustable, by

means of nuts J upon their upper ends, and.

the latter of which are supported uponadjusting-screws K inthe bottoms of the vertical slots in the posts I. The shaft J has fast upon it near its middle a corrugated feedstrip of paper as a pinion with a rack to draw A the paper forward when the roller is turned. Fast upon but longitudinally adjustable of the lower shaft K are a series of shortrollers M, one or more of which (not necessarily adjustable) are locatedimmediately beneath the corrugated roller L' and serve to support the corrugated strip of paper in meshwith the roller L as it is drawn forward between the rolls. Part or all of the rollers M are provided with circumferential grooves to receive and support the rear ends of guides N, which n are hooked around said rolls in their grooves i and extend forward and rest at their front end.

upon a cross=bar A- of the framework", Figs.-

2, 6, and 9.- These guides N serve tosupport the paper in its passage from the feed-rollers L M forward to the slitting or cutting disks 0 O, which are fastened upon but adjustablelongitudinal'l-y'of' twoshafts P P, journaled' like the's hafts -I and K, in-verticallyadjustable bearings mounted in vertical.

guides in bracket-supports Q upon the framework. The bearings for the upper shaft'P disksO on" the shaft 1, which will be done. when it is desired to out the strip of paper 0 only-transversely (by means hereinafter deare suspended upon the lower ends of screwrods R, threaded through nuts upon the upper ends ofthefbrackets Q; and having fast upon their upper ends sprocket wheels S S,

Figs. 1 and 2, around whichwheels passes anendless sprocket-chain T, by moving which the wheels :may'be turned simultaneously to uniformly raise or lower the bear-in gs for the opposite ends of theshaft P. By. turning the wheels in one direction by means of the chain the .shaft P m'ay be raised and its cutting disks'O withdrawn from cooperation with the scribed) and not longitudinally.

U is the driving-shaft of the machineand has fa'st upon its-:right-hand end, Fig. I 2, a

cone-pulley V, overwhich the belt'from the counter-shaft isfp'assed and by means of' v which the machine may be driven at difiere ent 'rajtesof speed. A sprocket-chain W,

passed around asprocket-wheel X, fast upon the shaft U, and a'round'a smaller sprocketwheel'fast upon the shaft P, Figs. 1, 2, and

5, servesto drive the-shaft P, and the latter is-geared to the shaft P above it by intermeshing gears. Y upon theright-hand ehdof, the shaft, Figs. 2 and 5. i The two shafts PP,

carrying thecutting-dis'ks-O O, are thus continuo'uslydriven from the maindriving'shaft in the direction of 'the arro'ws in-Fi'g.16, and

theseveralpai'rs of cutting-disks will serve to out the paper-.strip'O' into. longitudinal strips ofdifferentwidths, according to: thelateral adjustment of the several pairsjof disks; along their. shafts'P'P. ersL Mare intermittently operated to intermittently advance thepaperO to the cutting-f disksby means hereinafter described. From; the cutting-disks the strips of paper pass forward ontothe upper surface of the cross-bar Al, Fig.6. The vertical front face of this: cross-bar A ;(or; a separate plate B, secured" thereto) cooperateswith a vertically-recipro cating knife O, carried-upon the rear side of a transversecross-head D", which is supported at-its opposite ends upona pair of vertically reciprocating connecting rodsEflwhoselower ends carry straps -F-, surrounding eccentrics G; fa'stupon the driVingshaftU, Fig.1, bymean's of which theic'rosshead D and knife teach .revolu- C are'reciprocated verticall a tion of heiving-jshafa- The exact con nection of theupper endsof; the-rods E with the cross-head D in the The feed-roll.-

present instanceis as follows: The cross-bar D. hasformed 'or i secured upon its opposite endsyokesH, Figs. 2 and 6; through" which ispassed a transverse shaft 1, extending the entirelength of the cross-head and projecting said uprights, Fig. 5., The purpose of the particular connection of the cross-head with the upper ends of the 'connecting-rodsE is. this: Whenever it is desired'toslit the paper C longitudinally, but notto cut itftrans- Versely, the .knife Omaybe thrownou'tof' operation by turning the shaft 1 a'half-revo- 'luti'on in its bearings in the upper ends of the connecting-rods E,such turningof the shaft having-:the eifect,*as will be apparent" from Fig. 6, of lifting the cross-head an'd knife relatively to the connecting-rods, so"th'at :when' so adjustedthekuife will not desc'e'nd far'enough to sever thepaper passed beneath positions by 'set screws or otherwise.

-it.l 'Theshaft maybeturned'byanysuitable means and be held; infits opposite adjusted IOO ' ltremains to describe" the means by which fthe feed-rollers L'M are-given their intermittent movement tointermittentlyadvance the paper to the cutting devices'and the means byjwhi'ch the'leng'th ofwpaper advanc'ed by these rollersat each intermittent movement of 3 them may belvaried-z and regulated and I gaged as desired, this. part of the machine constitu tin g in some respects the'mostbroadly novel and importantfeatu re'of myinvention; Loosely mountedupon'the left-hand endi-of the shaft K,Figs.-' 1,2,"and'10, is a =hol10w circular casing "or drum Q, provide'd 'upon' its exterior with" three fcircular flangesvforming between them two deep grooves Secured-t0 the periphery of the drum orcasingin: the bottom of the innerone ofthese' two grooves is the upper endof a strap R, which i's'wou'nd about-the. drum in thedirectionshown in' Fig.1 and has attachedto its depending-lower end: a heavy weight S. 1' Secured'tothedru'm at the fbottomfof thejouter'groove and woundhereinafterdescribedto a long crank arm U, fast uponthe'. drivinggshaft' U. 'Ih'e".weight S, acting through the strapR, tends to turn the' drum Q in one direction, whileat each revolution ofjthe driving-shaft U the strap 'T will be'drawn forward and turn the drum in the opposite direction, thereby lifting the weight S and theweight serving to turn the" in the opposite direction'is a second's'trap'T", extending downwardly and forwardly andconnected-at its forwardiend'in the manner drum'baokWard again asf' the revolution ofward by the drawing forward of the strap T- it will turn the shaft K with it, while during its backward movement under the action of the weight S it willturn upon and independently of the shaft. The forward movement of the casin g produced by its connection with the crank-arm U of the driving-shaft will therefore serve to turn the feed-rollers L M and advance the paper to the cutting devices, while during the backward movement of the casing under the action of the weight S the shaft and feed-rollers will remain stationary.

In order to preventlost motion between the casing and shaft at the beginning of the forward movement of the parts and'at the same time not be obliged to employ a ratchet V having objectionably-small teeth, I employ the four pawls W, which are set in succession at increased distances from the respective teeth of the ratchet with which they cooperate at the forward movement of the parts. To illustrate, in the particular machine from which the drawings have been made the teeth of the ratchet V are a quarter of an inch apart, and in Fig. 10 the uppermost pawl W is shown in direct contact with thetooth of the ratchet with which it cooperates at the forward movement of the casing Q, while the succeeding pawl on the right is withdrawn one sixteenth of an inch from its tooth, the third pawl two-sixteenths of an inch, and the fourth pawl three-sixteenths of an inch. In this manner and by these means a ratchet having one-quarter-inch teeth may be employed and yet the feed be regulated vanced at each revolution of the driving-shaft may be varied as desired. The crank-arm U is provided with a longitudinal slot, in which is fitted to slide a nut X, Figs. 1 and 2, from which projects a stud Y, fitting an eye in a connectingpiece Z, fastened to the lower forward end of the strap T, a nut Z servingto confine the parts. Extending longitudinally of the arm U and through its slot is a screw-rod Z, which passes through thenut X and is free to be turned in its hearings in the crank-arm U at its opposite ends, but is held fromany longitudinal movement. The outer end of the rod Z is squared or otherwise suitably shaped to receive a wrench for turning the rod, and thereby adjusting the nut X and connection of the strap T longitudinally of the crank-arm U. As will be readily understood, adjustment toward the shaft U will shorten the movement communicated to the feed rollers L M at each revolution-of said shaft, andadjustment away from the shaft lengthens it. The crank-arm U is provided with a scale extending longitudinally of it and indicating inches and fractions of inches, so that by adjusting the connecting-point of the strap T longitudinally of the crank-arm U the parts may be set to advance any desired given length of the paper strip at each revolution of the driving-shaft U, and as the transverse knife 0 is reciprocated once at each revolution of the driving-shaft this adjustment will therefore determine the exto take care of the paper advanced to them by the feed-rollers under all the different adjustments of the feed within the range provided. Where the paper is being cut into short lengths, the machine can be run at a higher rate of speed than where long lengths of the paper have to be advanced to the feedrollers at each revolution of the driving shaft, and I therefore employ the cone-pulley V, Fig. 2, as the driving-pulley on the driving shaft, so that-the machine may be drivenat different speeds, according to the lengths of paper being cut. for long lengths ofpaper, the feed-rollers I) M will be given one or more complete revolutions, according to the adjustment, andin Where 'themachine is set The cutting-disks IIO order to restrain them from being overthrown by their own momentum at the quick forward movement imparted to them I apply a brakestrap A to the shaft K, said strap'being fastened at one end to a fixed rod B, projecting from the frameworlgFigs. 2 and 5, and

passing over a friction-wheel C, secured upon the end of the shaft K and having hung to its front end a weight D. The shaftsJ K are geared together by intermeshin g gears E, Fig. 5.

Secured at its opposite ends to the rear sides of the vertical standards 1, Figs. 1, 2, and3,'

thence downward and forward and rest at their front ends upon the cross-bar Aof-the One set of these attachments framework. The-several strips of paper 0 passforward from the cutting-disks O o be several-strips longitudinally, but not to cut the topof the'framework and turned to wind all of such longitudinal strips transversely,

and to provide'for delivering one or more of the longitudinal strips from the machine in contin uous form in such instances while passingt-he remaining strips beneath the knife 0, I provide some of the guide-arms N, hereto? fore referred to, with upturned forward ends, as indicated by the dotted lines at a in Fig. 6. By placing one or more of such guide-arms beneath the strip which is to be delivered from the machine uncut .such a strip will be di-' rected upward over the rear side of the knife O and cross-head D after passing the cuttingdisksand may be wound upon a reel I-I,Fig.'

1, supported in bracket-arms I, secured to up the strip by'a belt K passing aroundja small pnlley'uponithe spindleof the reel and around a pulley L. upon the driving-shaft -U,

Figs. 1 and 2. In thecase of thestrips thus delivered from: the machine in continuous form no guideor presser arms G will beem-vv ployed tohold the strips down upon the cross: bar A andv direct them beneath the knife 0.

The horizontallongitudinally-slotted. cross-.,

bar F alsolserves tofsupport the detachable scoring devices, (shown in Figs. 7 and 8,)whi'chQ areemployed when it is desired to score thepaper G longitudinally for thepurpose of per-f mitting it to be readily bent along the linesof the-scores, but without cutting it entirely through, as iszdone by the cutting-disks O 0"."

If it bedesired to use the machine simply as a scoring-machine, the shaft P, carrying the upper set of cutting-disks 0, will be raisedby of paper to the machine and cut it into several narrower strips,and also score eachof the narrower strips longitudinally, in whichcase 1 thepairs of cutting-disks will be properly ad jus-tedlaterally of the machine for' cutting the paper into strips of the desired width and the scoring devices be adjusted betweenthelines of cutting-disks to scorethe several str1ps., 2 The scoring device shown in Fig. 7 is whatiiscalleda cutting-scorer, since it con'-' sistsof a knife adapted to cut through the corrugationsof the strip of corrugated paperfedto the machine,'while not cutting through These arms G" can be attached '7 the cutting-knife M is detachably secured to-a depending arm N", which is adjustably secured to the supporting-bani? bya bolt and thumb-nut O". The scoring of the corpermits the paper to be bent into rectangular and other forms, with the corrugated surface outside and the. plain surface inside. The scorer shown in Fig. 8 is a creasing-scorer, consisting of a' blunt creasing wheel or roller P", 'journaled in the lower end of adepending armQ, adapted to be adj ustably secured at'itsupper end to the supporting-bar F in thesame manner as the arm N in Fig. 7. The creasing-roller P simply breaks down i the corrugations of the paper 0 in longitudinal lines-and permits the paper'to'befolded into rectangular, and other'angular forms, "with the corrugated surface inside and the plain'surface outside. 7 It will be understood that the cutting and creasingscorers may be to score one or-more of: the strips in one way "and-theremainder in the other way or may removed when the other is to be attached;
